What is the function of ribosomes in protein synthesis?
A
To facilitate the binding of tRNA to mRNA and catalyze peptide bond formation
B
To replicate DNA strands
C
To transcribe DNA into mRNA
D
To transport amino acids to the nucleus
Verified step by step guidance
1
Understand that ribosomes are essential cellular structures involved in protein synthesis, a process known as translation.
Recognize that during translation, ribosomes facilitate the binding of transfer RNA (tRNA) to messenger RNA (mRNA).
Note that each tRNA molecule carries a specific amino acid, which corresponds to a codon on the mRNA strand.
Ribosomes catalyze the formation of peptide bonds between adjacent amino acids, creating a polypeptide chain that will fold into a functional protein.
Remember that ribosomes do not replicate DNA, transcribe DNA into mRNA, or transport amino acids to the nucleus; these are functions of other cellular components.
